v SCREEN ATTACHMENT FOR WINDOWS.

To all 'whom t may vconce/m:

Be it known that 1 CARL J. JACKSON, a citizen of the United States, residing at Superior, in the county of Douglas and State of Wisconsin, have invented a new and useful Screen Attachment for Windows, of which the following is a specification.

This invention relates to screen attachments for windows.

The object is to improve'the construction of the screen attachment shown. and de- No. 1,117,390, issued to me November 17, 1914, and to provide improved means for permitting and directing the exit of flies from thelinterior of a room, at the the entrance of iiies Ventilating the room. A further object is tov simplify the construction of the 'device by the elimination of some of the stamped metallic parts shown thus rendering it possible to construct the attachment with a minimum number of parts, and at a much reduced cost, and to provide a device-which may be readily applied to a window'of ordinary construction by an inexperienced person.

A full and complete understanding of the invention may be obtained from a consideration of the following detailed description,

taken in connection with the accompanyingV drawing forming a part of this Specification; it beingunderstood that while the drawing shows a practical'form of the invention, the latter is not confined to strict conformity therewith, but may be changed 'or modified so long as such Changes or modifications mark no material departure from the salient features ofthe invention, as speciiically pointed out in the claims appended hereto. In the drawing, in which like reference characters designate similar parts throughout the several figures pFigure 1 is an elevation partly broken away, of a window and frame of ordinary t construction as viewed from the inside, and

having my improved Fig. 2 is asimilar view, as seen outside.

' far described, the parts may be 'of the present device Vdividing beads or strips device applied thereto.

tion through the upper sash, and adjacent parte, showing the said sash in elevated posi- Fig. 4 is a similar view, with the upper sash in lowered position.

Fig. 5 is a detail vertical section oii the line 5-5 of Fig. 1.

In the drawing there is shown a" window frame or casing 1, of ordinary construction, provided, in the usual way, with a dividing 'bead or strip 2 and inner and outer beads for strips 3 and 4, thus producing the necessary Channels 5 and 6 for the upper and lower sashes 7 and 8, respectively. As thus all of the ordinary construction with the exception that it has been found advantageous with the use v to remove thevupper cross'bar of the upper sash in order to expose the upper edge of the glass for a purpose to be described. This, however,

is not cessfully with the said cross bar remaining in place.

A section of wire gauze 9 or other screen material is secured to the inner faces of the extending entirely across the upper portion of the window opening and being of a width sufficient to extend downwardly a Vdistance great enough to permit the lowering of the upper sash tance for ventilating purposes, and still extend below the upper edge of the glass `in the upper sash.

Fastening means preferably employed the dividing beads 2, washers 11 being interposed to receive the heads of the fastening devices so that the screen may not become dislodged therefrom. Binding strips 12, of thin metal are arranged at the ends of the strip of wire gauze and against the inner faces of the vertical portions of the dividing beads 2, the upper ends of said metallic strips 12 being secured to the beads 2 by the upper lower ends of the strips 12 each have a return bend 13 to be engaged by the lower fastening means 10. rFhus, the heads of such as screws 10 are obligatory, as the device may be used suc- 2, said section 9 a considerable disto secure the screen to fastening means 10. 'The the various screws 10 are covered by the strips 12. A horizontally disposed flat metallic strip 14 is placed across the top of the wire gauze y9 and is secured, adj acent'to its ends, by Screws 15 or other fastening means. It will thus be seen that the wire gauze screen 9 is ypermanently iixed within the window frame and at a point suliciently above the top of the lower `-sash vto permit of raising the same sufficiently for ordinary 16,-.'composed'of angular metallic plates having inwardly directed portions 17 are secured within the Vchannel dom-opposite .sides in-order' to ,preventthe toplbar `ofthe Alowerfsash .from striking the bottom of the screen 9.

Stops 23 similar to the stops 17 are located'within the channels 5 sutliciently below the upper sash 7 to arrest its movement, upon being lowered, and support the sash in ajposition with the upper edge of the glass thereof in proper relation to the outwardly inclined strip-18.

From the foregoing it will be seen that the more or less expensive structure shown in the aforementioned patent has been greatly simplified by dispensing with t-he metallic guide members carried by the screenframe, and in which are adapted to travel certain other members carried byfthe upper sash in its vertical movement within the window frame or casing, thus resulting ina material reduc-tion in the cost oi manufacturel What is claimed is z- 1. A window screen attachment including a'screen adapted to be secured within the uppeiyportion of a window frame, a horizontally. disposed strip hingedly connected q*- y along. one long edge. to the outer face of the screen'on a horizontal line, stops for supporting vthe said strip in an outwardly and downwardly inclinedposition over the upwhen the latter 1s in a lowered-position, and stopsfor supsashy in spaced `relation at its top ,to the strip in order to form a y exit;

2.
